The graphic is for Mason's Pet Theory only. It shows the entry point where I believe the HSCA showed it.
Sure, move the bullet impact more towards the front of the rib. But not too much or the bullet will be going through the right arm. The trajectory won't work for Mason's Pet Theory no matter where it strikes the rib.
(Personally I think the actual rib strike was more tangential. It's Mason's Pet Theory that has the bullet striking so nose-on.)
Nice graphics, Jerry. But, as usual, you have everything wrong.
First of all, the bullet missed JFK's head on his right side.
Second, you do not allow for the fact that JFK had moved significantly to his left by z271.
Third, you seem to think that JBC was turned completely 90 degrees. But his chest is facing Zapruder so his shoulders are turned about 65-70 degrees.
Fourth, you have his wrist too high. The bullet exited through his right jacket pocket and passed through the end of his jacket cuff and through the french cuff of his shirt. The wrist is pronated so that the back of his wrist (not the side of his wrist) is pressed against the chest (not his neck as you have it). The end of his jacket cuff over the back of his wrist cannot be seen as it is pressed against his right jacket pocket.
I know you don't agree with my position, but in order to try to "refute" it, you have to follow the evidence. You are just making stuff up. In order to refute the evidence of a second shot around z271 striking JBC you have to recreate the positions of the men accurately. Since the best evidence is a two dimensional low resolution film, we have to estimate a range of possible positions and show the path to the right of JFK's head to JBC's right armpit to the back of his wrist for this range of possible positions.
